To use these socks, simply put them on like you would with any other pair. They're great for all kinds of activities, from running to casual walking. Make sure the socks fit snugly around your foot but not too tight. When it comes to washing, use a gentle cycle with cold water to keep the merino wool in good condition. Avoid using bleach or fabric softeners as they can damage the wool. After washing, lay them flat to dry. Don't wring them out or put them in the dryer, as this can cause shrinkage. With proper care, these socks will serve you well for a long time.
